Traditional Test Access Points have shifted from

ANALOG COAX RF to DIGITAL OPTICAL RF

CPRI based testing is now needed for:

– RF Interference Hunting

– Remote Radio Installation

– C-RAN Performance Testing

Coax / Antenna Installation Problems

• Antenna jumper loose or not connected

• Jumpers connected to wrong antenna

port (especially on 4-port 700/AWS

antennas)

• Bad jumper or bad antenna

OVP

RRH Installation Problems:

• DC Power loose or reversed at RRH

(non-intuitive color scheme)

• Fiber connected to wrong CPRI

port (non-intuitive port labeling)

• Wrong SFP installed in RRH

RRH Equipment Problems:

• Will not communicate

• Tx Port Failure

RRH

OVP Installation Problems:

• DC power wired incorrectly

• 700/AWS fibers swapped at LGX

• Fibers bent too tight in OVP

• Alarm wiring incorrect in OVP

External Problems:

• High RSSI (external

interference)

• GPS antenna bad or

not receiving

enough satellites

2000 Basic Tests

CPRI Link Test– Physical layer

• Optical power

• Link rate

• Bit errors

– CPRI Layer

• Link state

• Frame count

• Round trip delay

Cable Test– Loopback test

– Fiber test

parameters

• Continuity

• Latency

• Length

• Optical power

• Insertion loss

SFP Test– In-Box SFP Test

– SFP Test

Parameters

• Mfg info

• SFP Type

• Optical Power

• Temperature

“Polling” Functions

• “Poll” the RRH for Information– RRH Inventory

– RRH SFP Info

• ALU (today)

• Ericsson (future)

• Major benefit: Technician can do a more comprehensive RRH installation test. No one else has this
